| Outline of Final Research Achievements |
The purpose of this research was to obtain basic knowledge for application of molecular hydrogen (H2), which is attracting attention as a new antioxidant agent in recent years, in the health and sports science field. As a result of this study, there was no effect of H2 intake on exercise-induced oxidative stress, and endurance performance. However, it was shown that H2 significantly suppresses the decrease in liver glycogen content during endurance exercise.
These evidences suggest that intake of H2 suppresses the utilization of liver glycogen during exercise via physiological action other than antioxidation. Further research is needed on the mechanism that H2 suppressed the utilization of liver glycogen.
